Fix WIC loader bug when using autogen+force-rgba32 #183

Closed walbourn closed 9 months ago

walbourn commented 10 months ago

When using mipmap auto-generation with WIC source files that are BGRA format, the format will not be supported if the driver does not report support for both D3D12_FEATURE_DATA_D3D12_OPTIONS.TypedUAVLoadAdditionalFormats and .StandardSwizzle64KBSupported.

The "workaround" is to use the force RGBA32 which is always supported, but this combination of flags is not properly validated. This fixes that scenario.
